Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterGelco Chimney Liner & Rebuild in Cherry Hill: What to Know First
We provide independent Gelco chimney liner and rebuild service throughout Cherry Hill, with most inspections scheduled within a few days and liner replacements typically completed in a single visit. Our flat-rate pricing means the estimate we give over the phone is the number you’ll see on the invoice. This page is for Gelco owners in Cherry Hill who have been told they need liner work, aren’t sure whether to trust the recommendation, and want a second opinion from a crew that knows these systems inside and out. Call (856) 543-2929 - a live person answers, 24 hours a day.
How Gelco Products Fail - and How We Fix Them
- Gelco Model SS flexible liner fatigue in Barclay Farm colonials. The 304-alloy flex runs in Cherry Hill’s older masonry chimneys often develop circumferential cracking after 15-20 years of thermal cycling, especially where the flue passes through the uninsulated exterior wall section. We sleeve with a heavier 316Ti alloy or transition to rigid DuraFlex where the chimney geometry allows, documented with before-and-after camera footage.
- Gelco Pro-Fit relining panel separation. The interlocking stainless panels in this system can gap at the seams when original installation crews skipped the factory-spec expansion gaps or used non-Gelco corner pieces. We measure each course, source OEM lock bands where available, or fabricate matched replacements - never forcing a generic panel to fit.
- Gelco top-mount termination corrosion. The 304-stainless rain caps and storm collars on pre-2010 Gelco systems show accelerated salt-air corrosion even inland in Cherry Hill, thanks to winter road-salt aerosol carried on prevailing westerlies. We upgrade to 316-alloy or copper Famco terminations with proper storm collar overlap, and we document the existing cap’s part number before removal so you know exactly what was replaced.
- Gelco poured-in-place liner slumping in oil-to-gas conversions. When Cherry Hill homeowners switched from oil to natural gas in the 1990s, some contractors poured Gelco liner slurry without adjusting the mix for the lower flue-gas temperature. The result is a liner surface that has spalled or slumped in the lower third. We remove the failed pour and install a properly sized stainless or HeatShield cerfractory sleeve rated for the appliance class.
- Gelco rigid liner joint backing out in tall chimneys. The twist-lock joints in Gelco’s rigid 316Ti system can separate in chimneys over 35 feet when thermal expansion meets inadequate support spacing. We install additional Gelco support plates at code-required intervals, or transition to a flex liner with proper tensioning where the chimney offset makes rigid impractical. The chimney either draws the way it should, or it does not - and we will not leave until we know which.
Our Gelco Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, notes your Gelco model if you know it, and books a Level-2 camera inspection. We do not quote liner replacement sight unseen.
- 2
Inspection and documentation. Our tech runs a camera from firebox to termination, capturing photos of every joint, seam, and surface defect. You see the footage on site; we explain what we’re looking at in plain English.
- 3
Parts decision. If OEM Gelco components are available and appropriate, we use them. If lead times stretch past burning season or the geometry favors an upgrade, we specify DuraFlex, HeatShield, or another professional-grade alternative - never builder-grade substitutes - and explain the trade-off before you sign.
- 4
Repair and testing. Liner installation, rebuild, or relining is completed by background-checked, uniformed technicians. We pressure-test or smoke-test every joint, verify draft with a manometer, and photo-document the completed work.
- 5
Written guarantee and cleanup. You receive the 90-Day Done Right Promise in writing, the inspection photos, and an invoice that matches the estimate. No arguing, no paperwork chase.
What Gelco Chimney Liner & Rebuild Costs in Cherry Hill

What moves the price: chimney height, accessibility (steep roof pitches common in Cherry Hill’s Kings Grant section add labor), whether the flue is straight or offset, and whether the existing liner can be extracted or must be demolished in place. Every estimate is free, itemized, and valid for 30 days. Call (856) 543-2929 for an exact quote.
Why Cherry Hill Homeowners Call Hearthstone Chimney Co. for Gelco Work
We’ve been in Cherry Hill long enough to know which subdivisions have the clay flue liners that failed in the 1990s, and which have the Gelco retrofits that are now coming due. Russell Haines and our crew have handled Gelco systems from the original Model SS runs through current Pro-Fit panels - we know where the factory specs changed, which parts interchange, and which do not. Our 90-Day Done Right Promise means if the draft isn’t right or a joint settles, we come back. In writing, no arguing. Most jobs finish in one visit, and the price we quote is the price you pay. We also service DuraFlex and HeatShield systems, so if your Gelco setup is obsolete or a different brand suits your chimney better, we’ll tell you straight.
FAQs
Original Gelco warranties on materials typically ran 10-20 years and were tied to the original installation contractor; most have expired by now. As an independent Gelco service provider, our repairs do not activate or extend factory coverage, but our 90-Day Done Right Promise covers our workmanship and materials regardless of the original warranty status. Call (856) 543-2929 if you want us to review your paperwork.
Many Gelco components remain available through chimney supply houses, though specific sizes and lock-band styles have been discontinued. We stock common diameters and can fabricate adapters or source cross-compatible DuraFlex or Olympia Chimney fittings when OEM parts are no longer produced. We’ll know what’s possible after we inspect and measure your flue.
A localized crack, single separated joint, or damaged top termination usually warrants repair. Widescre corrosion, multiple seam failures, or a liner that has shifted out of alignment typically means replacement. Our camera inspection shows you exactly which category you’re in - we do not recommend replacement when repair will serve. Call (856) 543-2929 to schedule.
Most residential Gelco liner replacements in Cherry Hill are completed in one day, including removal of the existing liner, preparation of the flue, installation, and testing. Tall chimneys, offset flues, or jobs requiring scaffolding may extend to a second day. We tell you the expected duration before we start.
A compromised liner allows flue gases, including carbon monoxide, to leak into wall cavities or living spaces, and permits creosote to accumulate in the chimney’s interior gaps where it can ignite. The risk is real, but so is the cost of unnecessary work. Our camera inspection shows you whether the defect is critical or can be monitored. Call (856) 543-2929 for a free, no-pressure look.
